Killing Floor cannot detect my card

[Chken]

Build UT2004_Build_[2004-11-11_10.48]

OS: Windows NT 6.0 (Build: 6002)
CPU: GenuineIntel PentiumPro-class processor @ 2133 MHz with 2028MB RAM
Video: No Video

General protection fault!

History: UWindowsViewport::TryRenderDevice <- UWindowsViewport::OpenWindow <- UGameEngine::Init <- InitEngine <- FMallocWindows::Free <- FMallocWindows::Free

This is what it says any time I start up the game
My card is a Geforce 8800, which it should be able to detect, and I was able to play the game until I havd the 1st vista service package installed
Any help will be appreciated

try updating your directx package to the latest, and install the latest video card drivers.
